A smart contract is a self-executing program stored on a blockchain. It runs exactly as written when predefined conditions are met.
Once deployed, smart contracts operate independently without human intervention.
Smart contracts are triggered by transactions sent to the blockchain. When a transaction meets the contract's conditions, the code executes and updates the blockchain state.
For example:
All actions are transparent and verifiable.
Smart contracts enable:
They allow financial systems to operate continuously without centralized control.
Smart contracts are used for:
They form the foundation of decentralized applications.
Most smart contracts cannot be changed once deployed. This ensures predictability but also means errors cannot be easily fixed.
Some protocols use upgradeable contracts, which introduce governance and trust considerations.
Smart contract bugs can lead to fund loss. To reduce risk, many protocols undergo third-party security audits.
Audits improve safety but do not guarantee complete security.
Key risks include:
Users should understand these risks before interacting with protocols.
This knowledge is useful for:
Smart contracts are the backbone of decentralized finance. Understanding their role and risks is essential for anyone participating in on-chain markets.
